“…To conduct such communication smoothly, a support system sends the remote instructor's instructions including the place of the work to the local worker. In some research, a teleoperated laser pointer or laser projector is adopted as a means of sending such instruction [4][5][6][7][8] This method enables a remote collaboration system to be realized with a compact device. The teleoperated laser pointer has been adopted as a tool to point at a target of a work for compact systems [6,7].…”

We proposed and developed a method to visualize the light path of a laser with jetting mists along light axis of a laser pointer. The estimation accuracy for the position of a laser spot occluded behind an object was improved when the light path of the laser was visualized. In this paper, we propose visible light path laser projector (VLLP) for remote collaboration. VLLP is equipped with a laser projector and a mist generator. With the laser projector, VLLP can instruct with not only a laser spot but also simple line drawings. Furthermore, we propose several VLLP application prototypes.

“…In the case of a remote support for on-site worker, two examples utilizing robots are GestureMan [5] developed by Kuzuoka et al and C-term [6] developed by Mikawa et al These systems, in which robots with mechanisms of some kind or other mediate between remote supporters and on-site workers, aim to smooth communication between these parties, and share the same fundamental research goals. However, the main point of these systems is to get the robot to re-create the behavior of the remote supporter; they have not been developed from the viewpoint of actively utilizing the functions of robots that humans cannot imitate.…”

To create a more efficient environment in which to perform remote maintenance, the authors propose a novel collaboration concept, called robot-augmented communication (RAC). In RAC a maintenance robot and an on-site human worker are assisted by another skilled human operator at a remote support center. By emphasizing the intentions of the remote supporter through robot functions that cannot be imitated by humans, RAC can provide effective support for the on-site worker. In the present study, as the first manifestation of RAC, featuring the projection capability of a maintenance robot, a prototype remote-collaboration system named SCOPE (sight collaboration by projection effect) was developed. This system consists of a projector unit with a camera, a multiple control unit (MCU) for video/voice communications, and PCs connected via a network. It has three key functions: creating a shared field of view between a remote supporter and an on-site worker, keeping meta-information related to objects in real space, and projecting meta-information onto the objects. The effectiveness of these functions was evaluated by experiments on two fundamental tasks-"comprehending a target object" and "transmission of instruction details"-involved in a typical maintenance operation. The experimental results show that each function is effective in shortening the time taken to perform the maintenance operation.

“…Some mobile robots, that support human's daily life, are guided by a laser pointer manipulated by a human [15] [16]. In some telecommunication support systems (terminals/robots) equipped with a laser pointer [17][18] [19][20], a human is able to make his/her intentions to another in a remote site clear and concrete by directing the laser pointer to a particular spot, and this makes detailed oral descriptions unnecessary. Moreover, it becomes possible to direct using pronouns, such as "this" or "that", by pointing a particular spot using a laser pointer.…”

This paper presents a guidance method using a laser pointer attached to a librarian robot and gestures consist of body movements. Our librarian robot, that is fixed in an experimental environment, is able to say greeting properly based on estimation results of human behavior using a laser range finder, talk with a library user with a natural language, search books depending on a user's request. When the robot explains where a requested book is in the library, it points out a target position using a laser spot while the body and head are also turned around to the direction of the target. This makes detailed oral explanations unnecessary. However, the robot cannot always point out a target position directly using the laser pointer. So we design three types of guidance using the laser pointer and the gestures depending on the library environment. Some experimental results reveal the validity and effectiveness of our proposed guidance method using the laser pointer and some gestures for our librarian robot. 19th IEEE International Symposium on Robot and Human Interactive Communication Principe di Piemonte -Viareggio, Italy, Sept. 12-15, 2010 978-1-4244-7989-4/10/$26.00 ©2010 IEEE 978-1-4244-7990-0/10/$26.00 ©2010 IEEE
